Waterproof Breathable Fabric for an Amazon Private Label Seller in Norway
An Amazon Private Label Seller approached us with a waterproof breathable fabric requirement for the Norway market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Elastic that lost recovery after three washes
- An interlining that bubbled after the first press
- A zipper puller that broke under pull test at the warehouse

What we specified
| Item | Waterproof Breathable Fabric |
|---|---|
| Client type | An Amazon Private Label Seller |
| Market | Norway |
| Order volume | 10,000 pieces across 3 specifications |
| Base material | Iron |
| Standard size | 80 gsm |
| Finish | Glossy Enamel Coating |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Iron and locked the tolerance before bulk.
- The finish was moved to Rainbow Iridescent Finish after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.

Result
- 10,000 pieces delivered inside the 10-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
